A Great Schism

Some people don’t like to make the distinction between conservation & preservation.  It is true that they overlap. Conservation is the one with the Teddy Roosevelt tradition. Conservationists indeed aim to preserve nature, but also recognize the special place humans will always have in it. Hunters are often great conservations, so are foresters and even loggers. These guys are rarely welcome at a meeting of true preservationists. Preservationists on the other hand can count among their ranks deep environmentalists, who sometimes believe that earth would be better off w/o humans, and animal rights activists, who sometimes put the “rights” of the beasts above the needs of humans.  

Deep environmentalism has all the attractions of a religion. Its strongest adherents resemble puritans in many ways, but there is no redemption for them or the human race. Of course, this is an extreme view held by fringe people, but the pure preservationist ideal infects many in the environmental movement & even more casual adherents often see preservation as the true religion. 

I am agnostic about this, but I don’t believe in intelligent design. That means that there is nothing humans can do that will “destroy” nature because “nature” is only a human concept. In the billions of year of earth history before human consciousness developed, plants and animals lived and died w/o consequence.  When MOST of the world’s species died out at the end of the Paleozoic era, it didn’t make a bit of difference. The disappearance of the dinosaurs was mourned by nobody until the modern kids found out about the great extinction and called it a tragedy.

I was happy to read the most recent Nature Conservancy Magazine. In an article entitled, “Beyond Man vs. Nature”, the Conservancy’s chief scientist explains that biodiversity and/or simple preservation should not be top goals. “The ultimate goal,” he says, “is better management of nature for human benefit.”  Follow the links if you want the details.  Suffice to say, everything in the article makes sense to me. 

Of course, there are places we choose to preserve mostly untouched.  I have visited the Grand Canyon four times. It still fills me with awe. We should preserve the Grand Canyon for future generations.  Let me modify that.  We should conserve the place. I enjoyed the Canyon by walking to the bottom on trails carved out by human hands.  I drove up there on roads build by men and machines. W/o those human improvements, the Canyon would be as inaccessible to me as the mountains of the moon and as meaningful as some great canyon that might exist on Venus or Mars.

We are humans.  We can understand the world only with our human intelligence and perceptions.  What gives nature meaning and what allows us to get meaning from nature is the interaction of us with it.  An old epistemological conundrum asks, “If a tree falls in the woods, and nobody hears it, does it make a sound?”  It is an insoluble problem unless you add more detail. If you are talking about the sound waves that our human ears interpret as sound, a tree falling in the woods certainly does this. But a sound also requires interpretation.  If nobody is there to hear it, all we have is physical phenomenon. 

My guess is that preservationists would generally say it makes a sound, even if nobody hears it.  A conservationist like me might be a little more human-centric and say that it does not. For me, sixty million years of dinosaur history had no meaning until it was discovered by human consciousness.

I have written on many occasions that sustainable and natural are overlapping contexts, but they are not the same and that sustainable, in both natural and human influenced system doesn’t mean something that last forever. Nothing lasts forever. Sustainable just means a system that goes a long time adapting to continuous change. A good conservation strategy strives for a healthy human population interacting with a healthy environment. We don’t have to keep our human hands off, in fact we probably should not leave very much of anything untouched. Human interaction does not always profane nature; the interaction done right can ennoble both. 

Conservation is a higher order activity compared with mere preservation, which is an abdication of responsibility in the guise of wisdom.  Conservation demands that you apply intelligence and ecological factors to sustaining a system that works for man and beast. We humans live in this world. If/when there is a world w/o us, it really doesn’t matter anymore. As long as we are here, however, it is our job to do things right.

Where My Trees Went

Forestry is special in its commitment to long-term stewardship and sustainably. I got involved in forestry because I love almost everything about it. I just feel happier in the woods. Alex has been coming with me on some of my visits.  He commented that everybody seems happy in the woods and I think they are.  The foresters are happy, so are the wildlife biologists, loggers and landowners.  

Forestry provides a great combination between short term efforts and long term dreams.  You get an uncommon combination that includes choices & accomplishments you can make along with something much bigger, on which all our success depends, that we can spend a lifetime trying to understand. I don’t have musical or artistic talent. I feel I have a kind of expression like those things in nature. I understand that my forest is part of a something bigger. I checked out where the water that ran off my land ended up. I posted stories about my harvesting and planning for future forests.  A couple days ago I got to see where the thinned trees go and how they turn into paper products.

The trees harvested off my land last month went to KapStone Paper Mill in Roanoke Rapids, North Carolina. The mill has been there since 1907, although not under the same ownership. The mill takes only pine and makes the kind of brownish paper used for bags and packing materials.  Next time I buy a bag of Kingsford charcoal, maybe the bag will have some of my fiber in the paper.  They produce paper with something called the Kraft process. You can read about it at the link.  The Kraft process uses a wider variety fiber sources than most other pulping processes. The important part for me is that it can use all types of wood, including the resinous southern pine that we grow.

They start off chipping the trees. The chips are heated and treated chemically. For the details of how this works, check out the link I mentioned above. They brought out three cups of fiber and water from various stages of refinement. The liquid was a kind of brownish color. I couldn’t help but think of the time Chrissy & I visited the Jim Beam distillery. They both have a kind of mash.  Of course, it was not the same thing in any other sense and there was no tasting at the end of this tour.

Paper making today is capital intensive and minutely coordinated. The big machines – They give them names, BTW, one called the Dixie Queen, for example – represent a big investment.  There is not much warehouse space to store the finished product, so everything runs through as quickly as possible. Trucks and trains are standing by to take away the rolls of paper as soon as they are good to go. Other inputs are also ready just when they need to be. The mill uses only virgin wood fiber to make paper, i.e. there is no post-consumer content. Lots of the chemicals used in the paper process are recycled over and over again. It is all a chain, with one event depending on the ones before, and since any stoppage is very expensive, they spend a lot of time making sure nothing breaks down.  It doesn’t take many employees to make the plant run. It surprises me every time I visit a modern facility. Factories were full of workers when I started working back in the early 1970s. Historical pictures and movies tell me that they were even more crowded before that. Parts of the KapStone facility obviously were designed for lots more workers, necessary with older technology.

The best part of the tour for me was visiting the guys working on the lines.  It is the kind of thing that restores your faith in the American worker. I met skilled and involved workers at every step.  They understood not only their own jobs, but evidently how what they did fit into the whole picture.  And they were eager to explain how everything worked.   
Most of the operation is computerized these days. The paper runs past at around 30MPH.  One of the guys explained that at that speed any little thing can cause a break, but the cause of the break will be way down the line.  They have cameras constantly recording the process, so they can go back until they find the place where it went wrong. This allows them to continually improve the process. One of the guys said something that was basic quality-control but worth repeating.  Results are what count, he said, but in order to get good results you have to have a process that you can observe study and improve. If you have the guys on the line articulating things like this, you know that your colleagues are really on the team. 

Paper-making requires lots of water. The water comes from the Roanoke River. The Roanoke river discharges into the Chowan and then into Albermarle Sound, the same places the water from my farms ends up.  I know it is silly but I feel a little propritary about it and I wanted to make sure the water was okay. They showed me their water treatment facility. During the short tour, I didn’t look at it in great detail. It has the usual settling, aeration & filtering. It was a serious operation. Remaining solids were deposited in a landfill on the site, which provides good wildlife habitat.  Our guides told us about improvements to the paper-making process that allow more paper to be produced with less waste. As a result, the landfill is filling up much less rapidly than anticipated.  The KapStone plant produces much of its own energy, producing energy from wood residues and from “black liquor,” a residue that remains after the paper-making process. In the old days, Black liquor used to be dumped into rivers and streams. Today it is a valuable biofuel that helps power the plant. After the black liquor has been burned off, chemicals used in the paper-making process are recovered from the ash and recycled. The KapStone plant relies on renewable biofuels  for about 60% of its energy needs. 

I was satisfied with KapStone’s commitment to the environment. It is important to me to know that my trees are grown, harvested and processed in an acceptable way. I can watch the growing part myself, but I have to rely on good people for the other steps. I found some. 

There are three things that I notice when visiting industrial plants. First, as I mentioned above, I am surprised at how few people it takes to produce so much. Second, there is so little inventory.  I remember working in factory warehouses groaning with products.  We filled orders from accumulated stock in those days. Today the products move right through plant, from raw material to buyer.  The third thing that has changed is that less is wasted, which translates into more efficient production and less pollution (which is waste, after all.) 

Let me tell you about the pictures. The top shows a truck loading pulp to move in the yard.  Below is a stationary crane that can move the wood around. Those are obvious, but the third picture down is a little harder to recognize.  It is a “de-barker” and it works very simply. The logs go inside and roll around against each other.  It knocks most of the bark off.  Below the de-barker is Alex, all grown up and manly looking.  The last picture is just stacked wood.  I just thought it looked cool.

Planning for the Forestry Future

We have big plans for my little piece of forest. I say “we” because the planning has grown beyond my expertise. Yesterday, Alex & I met with Eric Goodman from Kapstone, Frank Meyer from Gasburg Forestry and Katie Martin, a wildlife biologist to talk about plans for the Freeman property. The local hunt club also has a stake in all this, so I have to bring them in too.  As I described before, the woods have been thinned to different densities, to see which ones produce the best harvests. We will also use different management regimes to test for different outcomes. Some parts will be biosolids; others will be burned or treated chemically.   

This will be a kind of demonstration forest for this part of the Virginia Piedmont. Already there is talk of bringing 4H, Boy Scouts and school groups. We will probably put in a path. Although Brunswick County is a center for forestry in Virginia, there are few places nearby to see forestry at work. The advantage of our land is that it will have several different types of cutting and management within a short distance. I think it is important for people not involved in the business to understand it, especially understand the renewable and sustainable aspects.  Most people don’t understand this part. It shows in everyday expressions, like “Save a tree: don’t use so much paper.” There are plenty of reasons not to waste paper, mostly related to the energy it takes to make and move it, but using less paper in any reasonable sense does not make a difference in saving trees. You have to thin trees, whether or not you can sell the pulp to make paper. If you don’t thin, they die anyway from overcrowding or bug and if you don’t thin, even more of them die in these ways. It is like planting flowers or vegetables in a garden too close together. Land can be overgrazed and overused. It can also be “over-treed.” And the trees grow back. This is what I have learned over and over again as I look at harvested timber tracts. As I take pictures and document the growth of my forests, it is clear to see. I expect to have more total green growing in my forest next year, after the thinning, than we had this year before.

One of the more interesting parts of the plan is longleaf pine planting. We plan to mix longleaf with loblolly.  Frank looked at the dirt and told us that we needed to plant to longleaf farther down the slope, where the soil had more sand and less clay and where the microclimate would be a little more moderate. That is the kind of knowlege you can get only from experience and that is why I need the help of all these people who know local conditions so well. If things go as planned, we can harvest the loblolly in fifteen years leaving a stand of longleaf. Longleaf pine used to be very common in the south, but have lost ground, since they require specific conditions; most important is burning to get them started. In other words, longleaf pine is a fire dependent species that didn’t do as well when fires became less common.

Katie will come up with recommendations for wildlife habitat under the power lines. We can plant warm season grasses and a mix of wildflowers, she says. It won’t cost me very much, since we probably can get some cost shares from Dominion Power (it is under their lines and our activities will save them the worry of cutting as well as provide a little “green PR”) These plantings will help restore something like the habitat common in this part of Virginia hundreds of years ago. It will also give us a chance to see how well these habitats respond under local conditions. 

In some ways I am more excited about the grassy ecosystem than about the trees. I love trees and the longleaf will be treasures, if we can get them to grow well. (Once they get going, they are very robust, but the start is tricky, especially where we are, near the natural edge of the biome.) But as we talked about the future of this piece of ground, and plans for activities years from now, the big thinning to take place maybe in 2026, I realized that my chances of seeing big longleaf growing on my land are small and my chances of seeing a mature ecosystem is zero. I was glad to have Alex with me. He can bore young people with stories of the creation, when he is an old guy. 

The grass and forbs will mature this year and a few years from now they will form a working ecology.  I have reasonable confidence that I will be around to see that. The trees belong to the next generation. Understanding that fills me with an exquisite mixture of sadness and joy. I am glad that something will be around after I’m gone, but it reminds me that I will be gone.

The picture up top shows some longleaf seedlings near the Virginia-North Carolina border. They are just coming out of the “grass stage”, called that because it is really hard to tell the little pines from the grass around them.  You would not be able to see them during the summer, since they would be covered by and the same color as the grass. The grassy vegetation has to be controlled. In the natural run of things, a fire would do that, allowing the pines time to grow above the grass.  I was told that this was an old farm field, so the trees got a head start before the grasses came in. Some of the bigger ones in this stand have done that, as you can see in the picture.

Food TOO

They seemed to be going in opposite directions. The report I watched on “Globo Rural” talked about transgenetic crops. Much of the soy produced in Brazil (in the U.S. too, BTY) is genetically modified. The reasons are clear. It is easier to grow. One farmer in the State of Parana explained why he went completely over to genetically modified soy. He could use a lot less fertilizer, almost no herbicides or pesticides and he did not have to run his machines in his fields nearly as much.   

Transgenetic foods are labeled with a “T” in a triangle, so that consumers can recognize them. Evidently some people don’t like them as much and so are willing to pay more for non-T-modified products. Non-T foods are also sold to the EU. People there, no doubt egged on by strong domestic interest groups, want non-T products and are rich enough to pay the higher prices. I am not really sure about that term non-modified, since all the field crops we grow are significantly modified by plant breeding. I chose to use that instead of “natural” since they are also very far from whatever ancestor they had in nature. This leads me to the second article.

The second report on “Jornal Nacional” talked about organically grown food and labels proving that the food on the shelves is organic. 

To some people this means natural, but all that it really means is that the farmer did not use synthetic fertilizers, herbicides or pesticides.AND for the time being “organic” does not include foods genetically modified by specific biotechnological means. This distinction is also important, since almost all the foods we eat are genetically modified.All the apples you eat, for example are from clones.Apples do not breed predictably.The only way to guarantee a red delicious apple is to clone it.Every one of the red delicious apples (or other varieties as well) are the identical tree, genetically). But people who care about labels consider plant breeding a different category.

People favor organics for a variety of reason. Some people think the organic products are better for them.  Others say the organic products taste better. (This could be true, although probably more because organics often are grown by smaller, local operators who can cater to tastes.)  But a big part of the choice is that organics are perceived to be better for the environment. This last is not true. 

Organic farmers tend to be less productive (per unit of labor and land) than those who use a wider variety of techniques. I don’t want to make too big a distinction between organic and non-organic. Much of “non-organic” production, BTW, is very organic.  Dairy farmers, for example, produce and use tons of organic manure and most farmers follow rotations, planting nitrogen fixing legumes, for example, which add nutrients and organic materials to the soils. No farmer uses only synthetic methods. The difference is the organic farmer will not use any synthetic products in addition to organic ones. This makes them less productive, which is why organic products cost more.  But the environmental cost is harder to understand.  Less productivity means that more labor and land must be used to produce the same amounts of food, which means more land must be cultivated, leaving less land in a “wild” state. 

It seems to me that one of the best ways around this dilemma would be transgenetic crops.  As the farmer in Parana said, he chose to plant transgenetic soya because he could use less fertilizer, less herbicide, less pesticide and he needed to use his machines less in the field, i.e. burned less fossil fuel in the cultivation of his crops.   It seems like a win-win to me. 

Transgenetic crops can be very good for the environment since they require less of all the inputs that currently cause concern. Properly deployed, transgenetic crops could solve, or at least address the problem of lower yields for so-called organic crops. Something that produces more, on less land, with fewer inputs of fertilizer, herbicides & pesticides and lets farmers use less fossil fuel should be welcomed, don’t you think? Maybe we should come up with a new category that is environmentally friendly. It could include organic products and transgenetic ones that use fewer of those inputs above.

We can call it trans-genetically- organic. How about this? We call it a Transgenetic- Organic-Operation for food production. The label can be “Food TOO.”

January Forestry Visit

Let me finish off my pictures from my forest visit. I went to both the tree farms. Let me caveat that this is the least attractive time of the year to visit, but also the most revealing because all the summer vegetation is gone and the stalks are as far down as they will ever be. I saw some ice-storm-wind damage at the CP tract. I didn’t take any pictures. I think that most of the trees will recover. Few are broken; a few are bent or leaning. The water is all running very clean. The boys and I laid some rip-rap last year and that succeeded in stopping erosion on the first little stream.

More about forestry is at this link

I like the stream management zones because they have big trees. They are mixed woods, with lots of big beech trees, as well as all sorts of oaks and tulip trees. There is lots of holly in the understory. Above is a picture of the SMZ where the road crosses taken with my new panoramic camera feature. Below is another beech showing the scares of a fire many years ago. Beech have thin bark, so it must not have been too hot a fir. The SMZs are moist, so maybe the fire couldn’t take hold.This tree is at the edge of the SMZ, so what I have not figured out is why the fire scar is facing TOWARD the moister ground and water of the SMZ.

Below shows the roots of another beech reaching down the hill at the SMZ.  It doesn’t have any significance. I just thought it was an interesting picture.  That tree is only a few yards from the fire scare tree, but it I couldn’t find any evidence that one burned. Maybe it all healed over. Eventually, the evidence gets covered. The rough bark probably hides some of that. As a city boy, I notice something else strange about my beech trees.  They don’t have initials carved into them. Beech bark is very soft and in any urban park they are covered with marks from generations of kids.

Below are rocks on the Freeman tract. We are not far from the Vulcan Quarry and I have a lot of boulders on this property. The rocks are attractive.  They demonstrate again the truth that value depends on location. I see boulders over at the garden center that cost hundreds of dollars.  My problem is that I cannot move these things with any reasonable amount of effort. 

The bottom picture is one of the loading decks used for the recent harvest. They did a good job of protecting the soil.  It is hard to see, but it is not packed down. This spring, the vegetation will grow profusely, creating great forest edge and bobwhite quail habitat. I will take another picture in June. It will be very different.

A Great Forestry Job

I visited the farm to check on the thinning. You can see the plan at this link. Frank Meyer and Gasburg Timber did a great job. If this sounds like an endorsement, it is. You can see Gasburg loggers in action (on a different tract) at the links here and here. You can see for yourself from the pictures.  They left healthy trees w/o signs of damage from the machines or activities.  You won’t be able to see how they took care of the soils at the loading decks and used the slash to cushion the weight of the machines in the stands of trees. The picture above shows the “lightly thinned” trees, leaving a basal area of 100. Below is the stand from the front gate.

below is a heavier thinning, down to 80 basal area. A little more than half the total trees were removed. With the 100 BA it is a little less than half. I like the park-like appearance. It reminds me of the ponderosa pine out west. And for the first time I was able to walk through the woods in relative comfort. But this is humid loblolly Virginia, not dry SW ponderosa pine forests. The openness won’t last. When the sun hits the ground, the brush will grow thick. By June, there will be chest high green and probably prickly. Good for the wildlife (the quail will love the overgrown corridors); hard on the guy (i.e. me) walking through. 

Below is the 80 BA from the road. You can see my truck on the top of the hill, for comparison.  These trees were planted in 1996, so they have been there for 14 years and are 15 years old. 

The thinning will allow the trees to grow a lot faster. They were just about reaching the point where they would compete too much with each other for light, water and nutrients. Now there will be enough of everything. The decaying slash will provide nutrients for the next couple years. After that, when the canopy closes again, I will do a burn of the undergrowth and then apply biosolids. Everything in the appropriate time. Feed the trees when they need it and can use it best. There would not be much use doing those things now. I would be afraid to burn with all that slash and if we apply biosolids before the trees can shade out out the brush, biosolids will just make it grow that much faster. I have nothing against brush, but I am not in the brush business.

Below shows the stumps from the thinning. Below that shows one of the stumps with my foot for comparison. Notice from the rings that the tree grew consistently fast, but this was probably the last year it would do that before the competition set in. All the trees would grow slower and within a few more years, some of them die, doing no good for anybody and creating both fire hazards and an invitation to pests, like southern pine beetles. 

It is hard to tell, because they are well camouflaged, but below are wild turkeys. I couldn’t get a great picture because they fly off when they see you. I don’t have the patience or skill to do active good wildlife photography. I like to take pictures of trees. They don’t spook or move. Turkeys have good color vision. I was wearing my red coat, so they could see me a long way away. There were at least ten of them.

I went to the other forest too and have some pictures and comments from that one. I will write some more tomorrow.  

Mud Slides & Popular Politics

It takes a brave man – and one with a secure job – to tell the truth in the face of great “natural” tragedy.  I saw that today on “Bom Dia Brasil”, where commentator Alexandre Garcia talked about the recent mudslides in Brazil that killed hundreds of people and left many thousands homeless.

The cause is easy to identify. People build dense settlements on steep hillsides, destroying trees and natural cover. This results not only in their own houses being destroyed by mudslides, but also can affect those down the hill who didn’t do anything wrong.

Garcia points out that Brazilian politicians love to make rules, but are less enthusiastic about enforcing them.  (This is not limited to Brazil, BTW. We have mudslides in our country true for some of the same reasons.) It is already illegal to build houses on most of the affected hillsides. But the poor, and sometimes the not-so-poor, invade the green zones and nobody has the political will, or maybe the actual force, needed to stop them. Local politicians, and sometimes even those at the Federal level, play the victim card and pander to voters. It seems unjust to not allow the poor people to have a place to live. There is also little support to solve the problem among the more established parts of the population, who are happy to have the poor living somewhere else.

And each time the predictable “natural” disaster happens, everybody can show solidarity and stick together to overcome the trouble.  Politicians can take credit for “solving” problems everybody should have avoided. Garcia says that the Governor of the State of Rio de Janeiro, Sérgio Cabral, knows what everybody knows:  populism helped kill people. (Sérgio Cabral sabe o que todos sabemos:o populismo ajudou a matar.) But what can you do about it?In the mountains of the Serra Gaucha in the southern state of Rio Grande do Sul, there are very nice towns such as Gramado & Canela. They are built in the mountains and are surrounded by steep slopes. But they rarely experience these sorts of problems because the slopes are covered with trees and vegetation that protect the soils.  As Garcia pointed out, this is also part of Brazil. Above is based on what Garcia said. Don’t blame him for the rest, which is my extrapolation.

Finding space for people to live in growing cities is always a challenge, but you have to recognize real options and constraints.  It doesn’t matter if the people and the politicians want to build houses on steep hillsides.  They cannot do it and expect not to suffer dire & deadly consequences.  

In other words, expanding in steep and unstable places is not an option and cannot be made an option by anything government can do.  Some places need to be protected, not to achieve some abstract aesthetic perfection, but because the immutable laws of physics and ecology forbid some kinds of development. It will rain. Mud will slide. If your house is in a place where the dirt moves, you will slide with it. If you remove the vegetation, even more mud will slide and destroy houses and vegetation that would not otherwise be affected. In other words, if you build houses on an unstable slope, you are responsible for significant property damage and maybe for murder.

The government’s role here is more difficult. It has to go against the manifest “will of the people” and constantly suffer criticism. Those enforcing the rules will be characterized as heartless, mean and cruel. Inevitably, a few people will occupy part of the preserved area.  How hard will it be to evict these people, who seem to have no other option?  How much can “a few” little people hurt the big hill? And how can it be fair not to allow more if you allow some?  You see the problem.

Preserving land in steep places is a never-ending challenge and not always as simple as just leaving things alone (although that can be far from simple, as I mentioned above). I read about the forests and meadows in Switzerland.  That very pretty and effective environment has been carefully managed by the human inhabitants for centuries and many lessons were learned. Sometimes they cut too many trees, but sometimes they didn’t cut enough.  In 1876 they made a law to prevent deforestation. Today forest may be becoming too thick. A dynamic balance is what we need. I wrote a little about the dilemma at this link.

An ecosystem is a living thing in the state of constant change. What works today might not work tomorrow w/o modification. The Swiss established forests on slopes where nature would not have put them, since frequent avalanches knocked them down. Once established, however, the trees helped prevent further avalanches and became mostly self-sustaining. I say mostly, because there is sometimes a disturbance that kills the trees locally. If they were not quickly reestablished and a meadow formed on the steep slope, snow would slide quickly down that area, destroying forests below, expanding the treeless area until you had again the unfavorable “natural” conditions.

The Swiss learned how to manage their mountains through centuries of hard experience and no doubt sometimes paid terrible prices for their education. The people in Gramado have evidently also come to equilibrium with their mountains. Gramado looks a lot like Switzerland, since its Italian and German immigrants brought their building styles. Maybe they also brought some of their forest management skills.  

In any case, the sooner others can learn the better. Many disasters can be avoided. Then maybe we won’t need the heroism we saw in the wake of the recent tragedies.

PS – I have some experience in mud sliding on a smaller scale. I have seen that the ground is always moving near my creeks. It doesn’t hurt anything and it is interesting to watch the changing conditions. It doesn’t hurt because it is just moving dirt from one natural place to another. During a big rain last year, it looks like the water rose at least five feet above the usual water surface and deposited mud many meters away from the creek. The water soaked in and the mud deposits will help fertilize the woods. If you had houses there, however, they would have been severely damaged. Even worse, they would have prevented the natural process.  There are some places that are not suitable for some uses.

The Worms Crawl In

This is something that just never occurred to me. 

I was watching a gardening show today about worms. Gardeners usually like worms. They help the soil remain fertile and aerated. That is what I always thought. But when I looked it up, I found out that worms are an invasive species. All those worms (night crawlers and the like) I remember as a kid were introduced from Europe.

Earthworms are destructive to forest soils, according to what I found at a University of Minnesota associated webpage.  Worms were wiped out by glaciers during the last ice age, which retreated only around 10,000 years ago. Without human help, worm populations move very slowly. Northern ecosystems developed in a worm-free environment. When worms arrive, they change the ecology. Evidently the worms eat the organic material too fast, taking away the layers of humus that all for the reproduction of forest floor plants and trees like sugar maples. Worms are small, but there can be lots of them and they don’t stop.

I never knew this or noticed it. The maple forests around Milwaukee already had earthworms, so I thought that was natural.  It still seems pretty strange to me that earthworms could be a threat. I suppose that when you are talking about long-established ecological relations, almost anything new that comes in can be disruptive.

BTW – honeybees are also not native to North America and neither are a lot of the flowers we see in fields, along with most farm animals and most crops we eat. Actually, I suppose that I am an invasive species, so I am not sure I buy into the native is better idea as a general construct. I will have to find out more about it.

The picture up top is one I took way back in September 2003 near the Milwaukee Airport, it shows the northern hardwood secondary growth forest.  We made a trip across the U.S. in 2003.  I kept up a webpage, it was the predecessor of my blog.  The link is here

New Forestry Plan

There is an exciting (at least for me) development in my forestry business. I am working with Eric Goodman from the KapStone Mill in Roanoke Rapids, NC to make our Freeman property into a kind of experimental/demonstration tract. 

We are going to thin to different densities, with two residual basal area targets of 80 & 100. In addition to that, we will have a five acre control block where no thinning or treatment will be done and another five acre area (labeled “CC”) that will clear cut and replanted with a combination of loblolly and longleaf next year. 

Planting longleaf is particularly interesting. Longleaf pine (pinus palustris) was once common throughout the south. It is a beautiful big tree, that forms in grassy groves and park-like palisades. But it is hard to grow and fire dependent, so it has not been propagated as much loblolly.

A National Wildlife Federation study says that longleaf pine ecosystems may be particularly well adapted to expected climate changes. The longleaf is well adapted to extremes that might become more common in the Southeast. You can read the study at this link about longleaf and climate change.

After thinning, we will experiment with other management techniques, such as burning, herbicides, pruning and fertilization.  It seems like it will keep us busy.

The picture/map up top shows the plan.

Loaded for Bear

Hunting is good. It puts people in close touch with nature and enobles both. But hunting evokes strong emotion. NPR ran an article about a girl in Mississippi who likes to hunt deer.  It got more than 500 responses, so far.  These things usually get one or two.  Of course, the anti-hunting voices were louder, especially on NPR, but a poll that went along with the piece showed that around 70% of the people liked the article.  

The State of New Jersey is allowing bear hunting this season. There are an estimated 3,400 bears in the state, up from only 500 in the 1990s.  State officials would like to reduce the number by around 500-700.  Hunting at the expected levels won’t be enough to reduce the population by these numbers, since past hunts have yields only around 300 bears. What they need is a yearly hunt to create a steady and experienced bear hunting population. Unfortunately, no bear hunts have been held in New Jersey since 2005.  Animal rights folks often dislike lethal wildlife management and they have sometimes been successful in getting judges to suspend hunts.

Around 6500 bear hunting licenses have been sold, of course few of these guys will actually successfully shoot a bear and most will not even encounter one, maybe because of the lack of experience mentioned above, hence the probable yield of around 300 bears.  Currently, New Jersey bear hunters can use only shotguns and black powder to bag the bears.

As I mentioned in an earlier post, bears have been spotted with increasing frequency around our farms. The bear population is growing down there too. I remain unenthusiastic about bears in my woods. They are generally harmless, but the qualifier “generally” worries me. I like to take my lunch with me. I don’t want to worry about attracting the big hairy beasts by leaving my ham sandwich on the seat of the truck and I would prefer to be easily the winner in any potential wildlife struggle. Fortunately, I have reasonable confidence that the bears will be kept under control on the farms.  We have lots of well-armed hunters in Brunswick County, loaded for bear.

The greater problem nationwide is that the number of hunters is declining. Hunting is something rural people do more than urban ones, so when the rural population shrinks, so does the hunting population. Beyond that, more and more land is being closed to hunting. I am glad to have hunters on my land, but not every landowner is so enthusiastic.

Meanwhile the populations of many animal species are exploding. There are more deer in Virginia today than there were in 1776. They have learned to thrive in close proximity to humans.  The same goes for coyotes, raccoons, woodchucks, squirrels and many others. Turkeys have made a successful comeback and I am afraid that bears are next.  Animal populations will get out of hand.  This was hard for me to believe a few years ago.  I grew up when wild populations were generally much lower and sometime locally endangered. Those times have passed for most game animals.  Hunters are now the “endangered species” in many locations. 

The alternatives to volunteer hunting are much more expensive and troublesome. Imagine creating a government bureaucracy and hired bureaucrats as hunters. Hunting requires reasonable skill. Hunters spend a lot of time exposed to the weather. They get up early and suffer in silence.  Imagine hiring somebody to do that.  Think of the overtime you would have to pay?  Now imagine hiring someone to do it and him joining some kind of public employees’ union. I suppose the animals would be safer.

Endangered species no longer

Related to hunting is an announcement that grizzly bears and wolves may be taken off the endangered species list.  These species have made a comeback. Nature is resilient & species that are/were successful can leap back. The problem for many endangered species is that they were marginally successful in the natural environment.  The very cute panda bear is a good example. The species is headed toward an evolutionary dead end.  It cannot reproduce well; it eats only a limited type of food, for which its digestive system really is not well suited to process. Human intervention just pushed it sooner. Wolves and grizzly bears don’t have this problem.

Populations of wolves and bears can be managed and should be managed by hunting, among other tools.  the endangered species law doesn’t allow for much flexibility. It assumes, as it must, that larger populations are better. But with a healthy population, this is not always true. In fact, a smaller, more genetically diverse population, might be better than a large one with different characteristics. A commitment to preserving each individual is rarely a good idea when you are talking about species. All animals are not created equal. Nature is not concerned with rights.

We also need to decide  WHERE endangered species should be defined. EVERY species on earth is “locally” endangered somewhere because every species range ends somewhere. Take the example of the common and familiar sugar maple tree. It grows from Canada to Florida, but it is common in some places and thin in others. Eventually, it just peters out at the end of its range. If you made a map with all U.S. counties where sugar maples had ever grown, you could argue that the species was locally endangered and even extinct in some places where it had once been reported to have lived.  If you looked hard enough, you could identify local varieties that could be declared endangered or extinct. And you could call it science.

Wolves are a successful species, but we would not want them to re-inhabit every place they were found in 1607. This does not indicate a failure of wolf protection.

I used to study wolves way back in the 1970s when I still thought I would have a career in wildlife and forestry. Experts believed that wolves were doomed and that the best case scenario would be to slow the loss. At that time, wolves lived in Alaska, a shrinking area in the arrow head region of Minnesota & on Isle Royale in Lake Superior, but they had not been seen recently in other places in the U.S.  Today the population has returned to places like Northern Wisconsin and the Rockies.  We won this. The wolves have been saved. Now we have to manage the populations.

IMO, we have to change the paradigm that includes the word “save” or features those dreadful countdown metaphors that imply soon it will be all gone. This may have been appropriate in the 1960s or 1970s, but today the better words would be some like “manage” or “prioritize.”  We are no longer defending the ever shrinking territory.  Now we have to figure out what to do with the options.
